Solving Differential Equations with Substitution Method

[der.physika]

I'm having trouble setting up this solution can anyone give me a hint, or set it up, so I can see if what I'm doing is right?

$$xy\prime=y=e^x^y$$

using the substitution

$$u\equiv(xy)$$

 

[kosovtsov]

$$xy\prime=y=e^x^y$$

What do you mean with two = in "equation"?

Sorry about that, I wrote that wrong the actual problem is

$$xy\prime+y=e^x^y$$

using the substitution

$$u\equiv(xy)$$
